Apical ballooning syndrome after attempted suicidal hanging

Insights into pathophysiology, management, and outcomes of near-hanging patients: A narrative review

Hanging is suspension of a person by noose or ligature around the neck. Hanging has been used as a judicial execution method since medieval times and is still a common method of suicide in developing countries. The term "near hanging" is used for those who survive long enough to reach the hospital, and these patients still hold mortality as high as 45%. These patients can present with a wide array of complaints involving cardiovascular, neurologic, and pulmonary systems and local injuries to the airway and vascular structures. High serum lactate and cardiac arrest at arrival are some of the prognostic factors which portend a poor prognosis. Early admission and aggressive treatment are essential to provide best neurologic outcome. Due to paucity of definitive guidelines, therapy has to be based on clinical reports and expertise of the treating physician. Hence, near-hanging patients pose a great challenge in primary emergency care and intensive care management. This review aims to outline the pathophysiology, prognostic indicators, and recent evidence in the management of near-hanging patients.

Clinical Profile, Corticosteroid Usage and Predictors of Mortality in Near-hanging Patients: A Five-year, Single-center Retrospective Study

Background

Hanging is the most common method of suicide in India. When near-hanging patients reach the hospital for treatment, their neurological outcome ranges from full recovery to severe neurological impairment or death. This study looked at the clinical profile, usage of corticosteroids and predictors of mortality in near-hanging patients.

Materials and methods

This retrospective study was conducted from May 2017 to April 2022. Demographic, clinical, and treatment details were collected from case records. Neurological outcome at discharge was assessed using the Glasgow Outcome Scale (GOS).

Results

The study involved 323 patients, 60% of men with a median (interquartile range) age of 30 (20-39). At the time of admission, the Glasgow Coma Scale (GCS) ≤8 in 110 (34%) patients, hypotension was present in 43 (13.3%) of patients, and 21 (6.5%) had hanging-induced cardiac arrest. About 101 patients required intensive care unit care. Corticosteroid therapy was given to 219 patients (67.8%) as part of anti-cerebral edema measures. Good neurological recovery was found (GOS-5) in 84.2% of patients, and the death rate (GOS-1) was 9.3%. Univariate logistic regression showed that usage of corticosteroids is significantly associated with poor survival (p < 0.02, odds ratio 4.7). In the multivariable logistic regression analysis, GCS ≤8, hypotension, need for intensive care, hanging-induced cardiac arrest, aspiration pneumonia, and severe cerebral edema were found to be significantly associated with mortality.

Conclusion

The majority of near-hanging patients had a good neurological recovery. Corticosteroids were used in two-thirds of the study population. There were multiple variables associated with mortality.

NT-proBNP on Cobas h 232 in point-of-care testing: Performance in the primary health care versus in the hospital laboratory

BACKGROUND

NT-proBNP may be useful for ruling out heart failure in primary health care. In this study we examined the analytical quality of NT-proBNP in primary health care on the Cobas h 232 point-of-care instrument compared with measurements performed in a hospital laboratory.

MATERIALS AND METHODS

Blood samples requested for NT-proBNP were collected in primary health care (n = 95) and in a hospital laboratory (n = 107). NT-proBNP was measured on-site on Cobas h 232 instruments both in primary health care centres and at the hospital laboratory and all samples were also analyzed with a comparison method at the hospital. Precision, trueness, accuracy, and lot-variation were determined at different concentration levels and evaluated according to acceptance criteria. Furthermore user-friendliness was assessed by questionnaires.

RESULTS

For Cobas h 232 repeatability CV was 8.5-10.7% in the hospital setting and 5.3-10.0% in the primary health care and within the analytical quality specifications, but higher than with the comparison method (< 4%). NT-proBNP results obtained in primary health care were significantly higher than by the hospital comparison method (bias ranged from 14.3-23.7%), whereas there was no significant bias when Cobas h 232 was used in the hospital setting (bias ranged from - 4.9 to 7.0%). User-friendliness of Cobas h 232 was overall acceptable.

CONCLUSION

Cobas h 232 point-of-care instrument for measurement of NT-proBNP performed satisfactorily with regard to precision, user-friendliness, and lot-variation. A decrease in NT-proBNP levels observed in samples transported to a central laboratory needs further attention and investigation.

A case of "Tako-Tsubo syndrome" with postoperative shock

The “Tako-Tsubo syndrome” is a rare, transient, reversible hypokinesia of distal part of left ventricle, with normal coronary arteries. It was recently described and frequently associated with an extreme stressful event in postmenopausal women. We report a case of “Tako-Tsubo syndrome” following elective surgery for oesophageal malignancy with septic shock. Our report highlights the electrocardiographic changes with the progression of this syndrome and the challenges we faced in managing the case.

Hanging-associated left ventricular systolic dysfunction

BACKGROUNDS

Although hanging injury is infrequent, its clinical course is usually devastating. Hanging patients usually need cardiopulmonary resuscitation (CPR). However, hanging-associated cardiovascular damage has not been fully established. The aim of this study was to evaluate echocardiographic findings in patients with hanging injury.

METHODS

We enrolled 25 patients (nine males and 16 females with mean age of 33±15 years) with hanging injury. Echocardiography was performed within 2 weeks after admission. Clinical, demographic, and laboratory data as well as transthoracic echocardiographic findings were analyzed.

RESULTS

Of the 25 patients, eight (two males and six females with mean age of 34±13 years) showed left ventricular systolic dysfunction (LVSD). Mean LV ejection fraction was 34±16%. Global hypokinesia was present in one patient. Apical ballooning with sparing of the basal segment was present in two patients. Basal akinesia and apical hyperkinesia were present in one patient. Four patients showed regional wall motion abnormalities unmatched with coronary territories. The duration of suspension or CPR was not significantly different according to the presence of LVSD.

CONCLUSION

This study showed the echocardiographic findings in considerable numbers of patients with hanging injury for the first time. Variable patterns of LVSD were present in patients with hanging injury.

A comparative study on reliability of point of care sodium and potassium estimation in a pediatric intensive care unit

OBJECTIVE

To compare sodium and potassium levels in children as done with Blood Gas Analyzer (BGA) at point of care testing in pediatric ICU vs. that done in laboratory electrolyte analyzer.

METHODS

This prospective method comparison study was done from February to April 2012 in Pediatric ICU of tertiary care hospital at Delhi. Sixty consecutive patients were tested during the period. Paired blood samples for venous blood gas to be tested on BGA and serum electrolytes to be tested on auto-analyzers (AA) were taken as per standard technique. Data was collected and 59 paired samples were analyzed for sodium and potassium levels. They were analyzed according to CLSI document EP15-A2 using ACB method comparison software.

RESULTS

Mean sodium measured on the BGA was 132.8 ± 12.2 mmol/L where as measured by AA was 141.5 ± 11.1 mmol/L. The mean difference between the two was -8.76 mmol/L (p < 0.001). The difference was statistically significant in all three subgroups of hypernatremia, isonatremia and hyponatremia (p < 0.001). Potassium level in BGA was 3.53 ± 0.81 mmol/L and AA was 4.28 ± 1.05 mmol/L. The mean difference between the BGA and AA was -0.75 mmol/L (p < 0.0001). The difference was statistically significant in patients with normokalemia and hyperkalemia (p < 0.0001). The difference was non significant in patients with hypokalemia (p = 0.051).

CONCLUSIONS

Blood gas analyzers underestimates Na + and K + values if sampling is done using liquid sodium heparin and if all other potential pre-analytical errors of testing are taken care of. The Bland Altman's analysis in the present study showed a significant systematic bias and very wide limits of agreement for both sodium and potassium, which is not clinically acceptable.

[Cardiac impairment after hanging attempt: a preliminary descriptive study]

PURPOSE OF THE STUDY

Cardiomyopathy has sometimes been reported after suicide attempts by hanging. The objective of this retrospective observational study was to describe cardiac dysfunction occurring after hanging and its consequences on prognosis.

PATIENTS AND METHODS

Fifteen patients admitted to the intensive care unit for hanging from 1997 to 2011 were included and divided into two groups according to presence or absence of cardiac arrest at initial presentation. Cardiac dysfunction was defined by the presence of clinical, biological, electrocardiographic or echocardiographic abnormalities.

RESULTS

Cardiac impairment was diagnosed in nine patients over 15 (60%). Of the six patients with initial cardiac arrest, only one survived without severe neurological sequellae. Among the nine patients without cardiac arrest, eight survived and five patients (56%) had cardiac impairment, including two cases of echocardiographic aspect of Takotsubo complicated by pulmonary edema. Mortality in intensive care was significantly related to the severity of the initial neurological state assessed by the Glasgow Coma Score (OR=1.7; P=0.02), and the occurrence of cardiac arrest (OR=40; P=0.016). The presence of cardiac involvement, reversible after the acute phase in all surviving patients was not associated with increased mortality.

CONCLUSION

In the aftermath of hanging, predictors of mortality are the presence of impaired consciousness or initial cardiac arrest, but not the occurrence of cardiac disease.
